Unclear It is not clear what the hooks now wait for or which sessions this affects.
What
Hooks are your own commands that Claude Code runs automatically at set moments, such as before a tool runs. Claude Code can now wait for a check to finish before it runs your hook handlers, and then carries on. A hook result can also be marked as having already run somewhere else, and Claude Code adjusts the hook's input when that happens.
Why
This changes the order in which hooks run and how some of their results are handled.
